The first signing to CTA Records is Margs, an MC probably best known for his association with the Mashtown crew.

Speaking to Clash, Wiley said: "I listened to [Margs] when he was really young, just because we're from the same area and my friend bought me the CD — they put a mixtape out ages ago and I just liked the whole movement, what him and his crew were doing. But then I realised that Margs has got, like, a fire. When he raps I feel his energy, d'you understand what I mean? I saw him on a Westwood freestyle and it was just energy."

Striking out on his own, new single 'What Have You Done?' is a deft fusion of classic grime tropes and 2k17 - the best of the old and new.

Rolling on that relentless production, Margs bobs left and right, before unleashing a few unstoppable upper-cuts. Tune in now.
